Where it sits in an outbound stack
Most outbound stacks are four layers: the data that decides who you talk to, the channel that carries the message, the writing that earns a reply, and the system of record that remembers what happened. Leadgenerator.io sits in the email sender layer. Tools beside it are worth comparing on coverage and price; tools in the other layers are worth wiring to it rather than replacing it with.

Leadgenerator.io sits on the email side of the stack. Mercury sits on the LinkedIn side and does not try to be your sending platform — Lead Finder returns a verified work email next to every LinkedIn profile and pushes it straight into Smartlead, Instantly, PlusVibe or EmailBison, so Leadgenerator.io keeps doing what it is good at while the connection request and the LinkedIn follow-up run in Mercury. One person, both channels, without the two lists drifting apart.
